Stackable Capsule for Coins, Tokens and Parts

This is a Stackable Capsule for Coins, Tokens and Parts

Secure your collection with modular coin tubes that screw tight, stack clean, and showcase your coins with precision-cut slots and a minimalist finish. Designed for makers who demand tactile satisfaction and archival reliability, these tubes elevate storage into a statement.

Four models are included:

• Short Version for 33 mm Coins. This is for coins with a diameter up to about 33 mm. It should work for American Gold Eagles, South African Krugerrands, British Gold Britannias, and the like. The interior tube has about 39 mm of space from top to bottom, which should hold 10-14 coins, depending upon thickness.
• Tall Version for 33 mm Coins. This is the same as the short version, only taller. The interior tube has about 69 mm of space from top to bottom. It should hold 20-24 coins, depending upon thickness. 
• Short Version for 30 mm Coins. For coins with a diameter up to about 30 mm. It should work for Canadian Gold Maple Leafs, and other coins of a similar size. Like the 33 mm version, the interior tube has about 39 mm of space from top to bottom, which should hold 10-14 coins, depending upon thickness.
• Tall Version for 33 mm Coins. This is the same as the short version, only taller. The interior tube has about 69 mm of space from top to bottom. It should hold 20-24 coins, depending upon thickness. 

The screw-top lid is designed so that the four sides line up with the four sides of the base when tightened. However, if the 3D printing process leaves blobs or other imperfections in the threads, it may be hard to tighten all of the way. Clean the threads and work it several times, and it will hopefully loosen up. 

Probably any filament will work here (except a soft TPU). But it was designed for PETG. 

Finally, a coin tube so secure it could survive a squirrel uprising, a toddler rampage, and three consecutive drops from your workbench without losing its lid or your sanity. With precision threading smoother than jazz and stackability that rivals pancakes at a Sunday brunch, this model doesn’t just store coins—it stores your faith in 3D printing.
